Boost Regulators
The CS5171/2/3/4 products are 280 kHz/560 kHz switching
regulators with a high efficiency, 1.5 A integrated switch. These parts
operate over a wide input voltage range, from 2.7 V to 30 V. The
flexibility of the design allows the chips to operate in most power
supply configurations, including boost, flyback, forward, inverting,
and SEPIC. The ICs utilize current mode architecture, which allows
excellent load and line regulation, as well as a practical means for
limiting current. Combining high frequency operation with a highly
integrated regulator circuit results in an extremely compact power
supply solution. The circuit design includes provisions for features
such as frequency synchronization, shutdown, and feedback controls
for either positive or negative voltage regulation. These parts are
pin−to−pin compatible with LT1372/1373.
Features Pb−Free Packages are Available Integrated Power Switch: 1.5 A Guaranteed Wide Input Range: 2.7 V to 30 V High Frequency Allows for Small Components Minimum External Components Easy External Synchronization Built in Overcurrent Protection Frequency Foldback Reduces Component Stress During an
